Study summary

This is a Phase III, placebo-controlled, double-blind, randomized study in participants with HeFH and elevated LDL-C to evaluate the efficacy, safety, and tolerability of subcutaneous (SC) injection(s) of inclisiran. The study will be multicenter and international.

Inclusion criteria

Participants may be included if they meet all of the following inclusion criteria prior to randomization:

  1. Male or female participants ≥18 years of age.
  2. History of HeFH with a diagnosis of HeFH by genetic testing; and/or a documented history of untreated LDL-C of >190 mg/dL, and a family history of familial hypercholesterolemia, elevated cholesterol or early heart disease that may indicate familial hypercholesterolemia.
  3. Serum LDL-C ≥2.6 millimoles (mmol)/liter (L) (≥100 mg/dL) at screening.
  4. Fasting triglyceride \<4.52 mmol/L (\<400 mg/dL) at screening.
  5. Participants on statins should be receiving a maximally tolerated dose.
  6. Participants not receiving statins must have documented evidence of intolerance to all doses of at least 2 different statins.
  7. Participants on lipid-lowering therapies (such as a statin and/or ezetimibe) should be on a stable dose for ≥30 days before screening with no planned medication or dose change during study participation.

Exclusion criteria

Exclusion Criteria:

Participants will be excluded from the study if any of the following exclusion criteria apply immediately prior to randomization:

  1. (NYHA) class IV heart failure.
  2. Uncontrolled cardiac arrhythmia
  3. Uncontrolled severe hypertension
  4. Active liver disease
  5. Females who are pregnant or nursing, or who are of and unwilling to use at least 2 methods of highly effective (failure rate less than 1% per year) (combined oral contraceptives, barrier methods, approved contraceptive implant, long-term injectable contraception, or intrauterine device) for the entire duration of the study. Exemptions from this criterion:

    1. Women >2 years (defined as 1 year or longer since last menstrual period) AND more than 55 years of age.
    2. Postmenopausal women (as defined above) and less than 55 years of age with a negative pregnancy test within 24 hours of randomization.
    3. Women who are surgically sterilized at least 3 months prior to enrollment.
  6. Males who are unwilling to use an acceptable method of birth control during the entire study period (condom with spermicide).
  7. Treatment with other products or devices within 30 days or 5 half-lives of the screening visit, whichever is longer.
  8. Treatment (within 90 days of screening) with monoclonal antibodies directed towards PCSK9.

The above information is not intended to contain all considerations relevant to a participant's potential participation in a clinical trial.

Terms in these criteria, in plain language(5)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

NYHA class (heart failure)

The New York Heart Association’s four classes of how much heart failure limits physical activity.

I
No limits: ordinary activity causes no undue tiredness or breathlessness.
II
Slight limits: comfortable at rest, ordinary activity causes symptoms.
III
Marked limits: comfortable at rest, less than ordinary activity causes symptoms.
IV
Symptoms even at rest; any activity makes them worse.

Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Postmenopausal

Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Nov 2017 to primary completion in Aug 2019, 20 months.

Results were first posted in Oct 2020, 1 year 2 months after primary completion.

Of 122 industry-sponsored phase 3 interventional studies under Hypercholesterolemia, half reached primary completion within 18 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 26. This study's 20 months is above that.

Counting every sponsor, half of 125 studies reached it within 18 months; a quarter within 10 and three quarters within 27.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Oct 28, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
